crushing of minerals

Inmineralprocessing or metallurgy, the first stage of comminution iscrushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition forcrushingrocks. In principle, compressioncrushingis used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones ...

    Crushing Minerals This technology increases the extraction of gold and associated metals up to 98% (possibly even more – everything depends on the initial ores and the gold distribution there). The basis of the proposed technology is Electro Hydro Impact (EHI) ores andtechnogenic wastage disintegrationand Magneto-Pulse (MP) flotation concentrates (gravity concentrates) and flotation tailings activation.

    May 01, 2016· Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have thetask of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.
